Abstract

The application discloses an information transmission method and an apparatus applied to a vehicle terminal, and is applied to an MCU or an MIPS arranged in the vehicle terminal. The method includes: firstly, to-be-transmitted information is obtained; according to the to-be-transmitted information, a corresponding message is generated, a header of the message includes N bytes, N is smaller than M, and M refers to the byte length of the header in an MODBUS communication protocol; and the message is then transmitted. According to the method, the capacity of the transmitted message is reduced, and bandwidth resources can be saved. In particular, the frequency of information transmission between the MCU and the MIPS is high and can usually reach the millisecond level, and much information can be transmitted so that a lot of bandwidth resources can be saved.

Description

technical field [0001] The invention relates to the field of information processing, in particular to an information transmission method and device applied to a vehicle-mounted terminal. Background technique [0002] The vehicle-mounted terminal is a device used for vehicle monitoring and management. It is generally installed in various vehicles. It integrates multiple functions such as positioning, communication, and driving records, and is used for dispatching and monitoring vehicles. [0003] At present, MCU (microcontrol unit, micro control unit) and MIPS (microprocessorwithout interlockedpipedstages, internal interlocking pipeline-level microprocessor) are usually arranged in the vehicle-mounted terminal. The MCU and MIPS are connected through a serial port, and can transmit information. For example, the MCU is connected to the CAN bus provided on the vehicle, and the MCU can obtain the information transmitted by the CAN bus (such as vehicle speed, gear position, power ...
